vino password not working after 2.16 upgrade

[Scott I. Remick]

So I've had an otherwise-successful upgrade to Gnome 2.16, but I've 
discovered my VNC/Vino password no longer works (and I'm remote now with 
only ssh access... normally I tunnel VNC over ssh).

The VNC client still prompts me for a password, so the fact that Vino is 
running is still being detected. But I keep getting "authentication failed".

Here's my ~/.gconf/desktop/gnome/remote_access/%gconf.xml file:

<?xml version="1.0"?>
<gconf>
         <entry name="vnc_password" mtime="1148297146" type="string">
                 <stringvalue>xxxxxxxxx</stringvalue>
         </entry>
         <entry name="authentication_methods" mtime="1148297144" 
type="list" ltyp
e="string">
                 <li type="string">
                         <stringvalue>vnc</stringvalue>
                 </li>
         </entry>
         <entry name="prompt_enabled" mtime="1148297143" type="bool" 
value="false
">
         </entry>
         <entry name="enabled" mtime="1148297139" type="bool" value="true">
         </entry>
</gconf>


I've run the password hash through a Base64 decoder and it's still what 
it should be (what it was prior to upgrading to 2.16).

All that's in my auth.log is:

Oct 23 09:20:19 scott sshd[51865]: error: connect_to 127.0.0.1 port 
5900: Connection refused
Oct 23 09:20:19 scott sshd[51865]: error: connect_to localhost port 
5900: failed.

Strangely, only once do those lines appear, despite multiple failed 
attempts.

This is a FreeBSD 6.1-RELEASE system, if it matters. Any ideas?
